TIRE.

Toall whom it may concern:

Be it known that I, BYRON C. Bowen, a

citizen of the United States, and a resident A.of Cudahy, in the countyof Milwaukee and State of Wisconsin, have 'invented a new and ImprovedTire, of which the following is a full, clear, and exact description.

This invention relates to vimprovements in tires or cases for wheels,and has for an object to provide an improved structure which tire inplace without theuse of=interlocking or clenching members.

Another object of the invention is to provide a shoe with an enlargementat the rim engaging portion together with a reinforcement comprising aplurality of strands of stili'ening members.

' A'y still further object is to provide an improvedsiniple strongconstruction for the rim engaging portions of a shoe or tire which willpositively hold the tire in place when the inner tube is inflated,butwhich will allow the tire or shoe to be readily removed when theinner tube is deflated.

In carrying out the. objects ofthe invention a tire structure of anykind may be used which is provided with annular feet or en` largementsor basesdesignedto engage the rim'of the wheel. Arranged in these basesections or portions are flexiblel fillers, and also anchoring devicesin the fom of cables -for thetoe and heel of the base whereby the sameis held properly againstv both the basel of the rim andv the -edgesthereof. This double cable base construction positively prevents thetire blowing off the rim andl causes a proper actionv at what may betermed the danger line Aof the tire, namely, the bending point at theedge of the rim.

In the accompanying drawings--Figure 1l is a section through a tire anda rim embodying the invention; Fig. 2 is a section through a slightlymodified form of tire showing the invention applied to a clencher typeof tire..

Referring tothe accompanying drawings by numeral, 1 indicates a tire of.any desired structure having. the usual side members 2 and 3 of rim forholding the tire 4 in position. The tire lef-may be made of any desiredstructurebut is provided with'bases 5 constructed so as to remain firmlyin place,

and to eliminate any pinching of the tubes Specication of LettersPatent.

- are constructed in such a manner that the line 6. At 'this 4linethe'tire must bend or ieX ywhile the'same is .in use, and the move'-ment must be easyand regular without anyl scraping against the sidemembers 2 and 3.

In orderto hold the tireproperly in place the bases A5 are 'madecomparatively sti-ii'. To allow the easy flexor bendin of the tire `eachof the bases is provided pre erably with a triangular filling 7 offabric impregnated with rubber, though other suitable material.

capable of being vulcanized may be used. A f

proper securing anchorage is provided by associating with the liller 7,the cables 8 and 9, one cable being arrangedat the heel of the base andthe other at the toe.l It will be observed that thecables 8 and 9 haveindi` blowing olf of the tire or the pinching of the inner tube.

The cables 8 and are made from Aun- .in position as shown in Fig. 1'.,It is tobe.

observed that these anchoring cables are near the bottom of the base andthe filling member 7 commonly known as the bead .filler falls short ofthe danger line 6, thatis,

i doesnot extend up tothe danger line 'sgthat the tire is allowed to Hex.or bend back and .reinforced portion, comparable in flexibility lwiththe material ofthe; casing itself.

I As shown in 1 the bases are provided with what are known asstraight'walls foritting members 2 and', but thebasesfmay be changedfrom the straight-walli structure to the clenched structurg as shown/inFig. 2, without departing from the' spirit of the invention. Referringto Fig.' 2 it will be obicc can be vulcanized to the tire served that aelencher iilling or extra bead ller 1s provided for each of the basesfor 'co-acting With the'side members 2 and 3, l which side members areoi a clenoher type,

The bead fillers may be made rubber or any other suitable material forproviding a good clencher member for the side inemliers or rings 2 and3.

What I claim is- .i l. In a pneumatic tire casing of the classdescribed, a, foundation base having ineluded therein a "filler membersubstantially triangular in cross section, having its apex portioncomposed of iiexible lling material and having its bottom 4side locatedclosely adjacent to and substantially parallel to the rim surface, saidfiller having' incorporated therein metallic exible reinforcing means.of comparatively small cross 'sectional area compared with the lcrosssectional area of the base, said reinforcing means being distributedover and confined to the bottom side of said triangley 2. In a pneumatictire casing of the class 1 describeie foundation 1oase having includedtherein a filler member substantially triangular in cross sec ion., itsapex )ortion bein ,fg composed ef-llemoie )filling material cap able ofbeing vulcanized to constitute an integral part of the baseliavingsubstantially 'the same physical characteristics as the car- A.
